All activities, whatever their content, have happiness as their target.
Yet almost every activity equates happiness with an object to be attained.
Yet happiness is not an object, let alone one to be attained.
Therefore, the explicit aim of almost all activities is at odds with the deeper, implicit aim, which is to be abidingly happy.
How is this to be remedied?
Simply let every activity–every perception, every sensations, every thought, and every feeling–long for, point to, and ultimately merge into its source. That source is Pure Consciousness-Absolute Being-Eternal Happiness.
This, indeed, could be called a Tantric approach to Vedanta in that every activity is allowed to unfold, with the proviso that one is watching as the activity submerges into its desireless essence: Being-Consciousness.
One is invited to “look on” all activities in this way, letting vritti (“thought-waves”) slowly come to a halt, to fruition in their source.
