As tapa is not a distinct spiritual path, what does Gita 6.46 tapsvibhyo adhiko yogi refer to?

Question. In Gita 6.46, Tapasvi bhyadiko yogi, the Acharyas say that the Tapasvi refers to 4.28 those who perform Tapasya as a Yajna.
So how is this exactly correlated? Actually, if we see in that particular verse, Tapasvi is not specifically one particular Marga. So Karma and Jnana are specific paths. So Krishna is saying that here that the path of Yoga is higher than those paths.
But then what exactly is Tapasya? That’s not a distinctive path, at least not in the broad categorization of Karma, Jnana, Dhyana and Bhakti. Tapasya can be called as an element of these paths, especially the path of Yoga. But in the section from 4.25 to 4.33, Krishna gives various kinds of Yajnas.
And there he mentions, there are Yajnas, Tapo Yajna, Yoga Yajna. There he also talks about Tapo Yajna basically. So there he’s talking about Tapasya as one particular kind of Yajna.
And those who do this as one particular kind of Sadhakas. So that is what is being referred to over here. Now, we can take this statement Tapasvi bhyadiko in a specific sense as well as in a generic sense.
Specific sense would be that, okay, Acharya Singh refers to 4.28. In a generic sense also, it means that just doing austerity, as Prabhupada writes in his Purport also, that he explains that how each of these paths are incomplete and how Yoga makes it complete. So mere asceticism without self-knowledge is not complete. So Tapasya is primarily negative.
That no, no, I won’t do this. I’ll give up this. I’ll avoid this.
But Yoga involves the positive also. Yoga means going inwards towards the connection with the indwelling Supreme Lord. That’s why in a specific sense, it can refer to 4.28. But in a generic sense, what it refers to is that just the negation.
So karmic bhyadiko means just action in this world is not as good as inner connection. Just renunciation or austerity is not as good as inner connection. Nor is just intellection.
Intellection means just intellectual analysis. That is not as good as inner connection. So the inner connection is more important, most important.
And that’s why this is higher. Now, the sixth sequence of what is mentioned is that what is that inner connection? When that inner connection is properly established in a devotional attitude towards Krishna, then that is the best. So in that sense, there is a hierarchy over it in these two verses.
Thank you.
